BAND-CUTTER AND FEEDER.

Specification of Letters Patent.

Application filed August 8, 1908.

Patented May 25, 1909.

Serial No. 447,609.

To all whoa/1, "it may concern:

Be it known that I, MARTIN GARLSON, a citizen of the United States,residing at Diamond Bluif, in the county of Pierce and State oflVisconsin, have invented certain new and useful Improvements in Band-Cutters and Feeders, of which the following is a specification.

This invention relates to threshing machines having special reference toan attachment to be applied thereto.

in object of this invention is to provide a threshing machine with aspreading cylinder whereby the grain will be spread out evenly as it isfed from the band cutter into the concave beneath the thresher cylinder.

Another object of this invention is to provide a machine for cuttingbundles which escape from the band cutter before they are fed to thethresher cylinder.

A further object of this invention is to provide a cylinder with aplurality of blades disposed at an angle to the axis of the same for thepurpose of spreading the clusters of grain which are fed from the bandcutter before the grain enters the thresher cylinder.

The invention has as a still further object the provision of a device ofthis character that can be raised out of operative position when desiredso as to gain ready access to the thresher cylinder.

Other objects and advantages will be apparent from the followingdescription and it will be understood that changes in the specificstructure shown and described may be made within the scope of the claimwithout. departing from the spirit of the inven tion.

In the drawings forming a portion of the specification and in which likenumerals of reference indicate similar parts in the several views,Figure 1 is a vertical longitudinal section of a cylinder of ordinaryconstruction, having the device applied in operative position. Fig. 2 isa top plan view of the same having the casing removed. Fig. 3 is avertical transverse section on the line 33 of Fig. 41. Fig. 1 is adetailed view of the spreading cylinder in side elevation.

Referring now to the drawings 10 designates the casing of a threshingmachine which is of ordinary construction and which is provided upon itsinterior with a concave 11 which is positioned centrally thereof beneatha threshing cylinder 12. The threshand is mounted upon the shaft 13transversely disposed within the casing 10. A cap 11 is mounted abovethe thresher cylinder in the casing 10.

The shaft 13 pivotally carries at its opposite extremity two arms 15 and16 which extend in a parallel direction therefrom and support in theirouter ends the spreading cylinder 17, the subject of this invention.

The casing 10 carries a band cutter 18 forward of the thresher cylinder12 which receives the bundles of grain and cuts the bands securing thembefore they are fed into the cylinder 10.

The spreader cylinder 17 is located intermediately of the band cutter 18and the thresher cylinder 12 for the purpose of intercepting the passageof and acting upon the grain it is conveyed therebetween. The spreadercylinder 17 is mounted upon a shaft 19 which carries at its oppositeends gears 20 which mesh with idlers 21 intermediately disposed upon thearms 15 and 16, the idlers meshing with the pinions 22 disposed upon theshaft 13 for the purpose of actuating the spreader 17. The spreadercylinder 17 comprises the shaft 19 which supports three equidistantlyspaced heads 23 which carry a plurality of metallic strips 24 which aredisposed spirally across the peripheries of the heads 23.

The strips 24 diverge in opposite directions from the center head 23toward the end heads 23 for the purpose of giving an outwardly feedingaction during the rotation of the same. The strips 24: are provided ontheir outer faces with longitudinal rows of teeth 25 and cutting blades26 which are alternately disposed thereon. The teeth 25 are employed forthe purpose of assisting and in insuring the proper spreading action ofthe grain and the cutting blades 26 serve to cut the small bundles whichescape from the band cutter.

The arms 15 and 16 permit the spreader cylinder 17 to swing up over thecylinder cap 1 1 and out of operative position for the purpose ofgaining easy access to the thresher 12 and to the band cutter 18 whennecessary.

The bundles of straw, grain or the like enter the front of the machineand are engaged by the band cutter 18. The cutter 18 cuts the bundlesloose and passes them in a loose condition to the spreader cylinder 17when the straw is evenly distributed to the ing cylinder is of anyadaptable construction 1 concave 11 by the outwardly feeding action ofthe strips 24. The threshing cylinder diverged across the peripheries ofsaid heads, then acts upon the straw and passes it teeth on said strips,and blades on said strips, through the machine. If any of the bundlesescape from the band cutter 18 Without being loosened the blades 26 uponthe cylinder 17 engage the same and cut the bands before it is spreadand fed into the thresher 12.

What is claimed is:

A threshing machine having a spreader cylinder, said cylinder comprisinga shaft, spaced heads on said shaft strips diagonally disposed in rowson said strips.

In testimony whereof I affix my signature, l in presence of tWowltnesses.
